RENEWABLE OR LOOSE LEAF BOOK.

To all whom it myconcem:

Be known that we, GEORGE ALFnEn I BENNE'rr, a subject of the King of Great Victoria, Commonwealth of-Australia, and

FREDERICK .BENJAMIN AnoLPH KIRSTEN, a subject of the King of Great Britain and Ireland, and a resident of the postal district of Balwyn, a suburb of the city of Melbourne, in the county of Bourke, aforesaid, have invented certain new and useful Imrovements in Renewable or Loose Leaf ooks, of which the following is a specification.

This invention relates to books having renewable or interchangeable leaves and more particularly to sales books, pocket books and other comparatively small books of that type. It will be evident from the following description, however, that the invention is not by anymeans limited to such comparatively small books but ma beapplied to other books of various kin s and sizes.

The object of the invention is to provide an extnemely simple and inexpensive means for retaining the leaves of a book within its cover in such a manner that they may be readily withdrawn and replaced or renewed as desired.

The invention is primarily applicable to books having single loose leaves adapted to be withdrawn and replaced independently of each other. I

But in order that this invention may be better understood reference will now be made to the accompanying sheet ofdrawings which is to be .taken as part of this specification. and read herewith Figure 1 is a perspective view of a book cover having aleaf holder, in accordance with the invention, attached thereto.

Figure 2 is a cross section.

I Figure 3 isva perspective View. of a block of single loose leaves retained together b adapted for use with the present invention.

Figure 4 shows in section a modified arrangement of the block of leaves and binding wire seen in FigureB.

a metallic binding wire or tape and also block of loose leaves seen in Figures 3 and 4 retained within the leaf holder.

According to the invention the book cover 2 is attached to the rear of a leaf holder 3 preferably formed of spring metal of substantially -U shape or C sha e in cross section as seen in Figure 2. he leaf holder thus forms a channel 4 having an open mouth 6 through which the leaves are passed lengthwise into or out of the holder. The sides of this mouth form opposite jaws between which the leaves are held. These opposite jaws may be provided with outturned edges 7, as seen in Figs- 1, 2 and 6, which prevent cutting or wearing of the leaves when the latter are being introduced or withdrawn.

One end of the channel 4 may, if desired, be bridged by tongues 8'01 entirely closed to prevent the leaves being pushed too far along the holder, whilst the other end is entirely open as at 9 to allow of the introduc- Patented Feb. 14, 1922.

tion andremoval of the leaves as hereinafter end 9 of the holder may be flared or diverge towards the adjacent end of the holder as in dicated at 11 to facilitate the introduction of the leaves.

The leaf holder 3 may be retained to the cover 2 by any suitable means, for instance by a retaining wire 12 which passes through holes in the cover and the back of the leaf holder respectively.

A block of single loose leaves 24 may be employed with the leaf holder. These leaves are interchangeably bound together by a metallic binding tape or wire 26 passing through holes- 27 or niches 30 in the leaves. The ends of the tape 26, which may normally spring outwards as shown in dottedlines in Figure 4 are turned down flat upon one of the outside leaves when introduc'ed into the holder, as shown in full lines.

Such leaves are particularly useful for note books and the like and enable individual leaves to be withdrawn and replaced without tearing from the book. A blockof leaves of which prevent them It will be evident that the springy nature of the leaf holder enables it to accommodate itself to blocks of leaves of different thickness, as when leaves are removed or added,

a the jaws at the sides-of the open mouth 6 ners; and a spring binding tape having its central portion arranged against one face of the block of leaves and its end portions inserted through said openings and projecting beyond the opposite face of said block, the projecting parts of said end portions having a tendency to spring outwards away from each other and from the block but being pressed inwards toward said block consequent upon the insertion of the block in the holder.

In testimony whereof We affix our signatures.
